"If, however, in our perversity we are still bent on constructing a sentence that does attribute falsity unequivocally to itself, we can do so thus:

`Yields a falsehood when appended to its own quotation` yields a falsehood when appended to its own quotation.

This sentence specifies a string of nine words and says of this string that if you put it down twice, with quotation marks around the first of the two occurrences, the result is false. But that result is the very sentence that is doing the telling. The sentence is true if and only if it is false, and we have our antinomy."
-- "The Ways of Paradox and Other Essays" W.V. Quine 1976

クワインとは、入力を取らず、自分自身のソースコードを出力するプログラムです。
このプログラムは、計算機科学分野では「自己複製プログラム」としてしばしば知られています。

実行環境中で自分を複製する関数"quine"を実装して下さい。
全体のコードを ANSWER_CODE とします。このコードはquine関数の定義も含みます。
quine() を実行した時、結果は ANSWER_CODE と同じ文字列になっている必要があります。
ローカル環境で次のようにテストすることができます:

exec(ANSWER_CODE);quine()

この問題のテストケースは1つだけです。ANSWER_CODEと関数の実行結果をそのまま比較しますので、改行、タブ、空白文字に注意して下さい。 ...
この問題の主たる目的は独創的な解答を作ることです。

CheckiO Extensions

CheckiO Extensions allow you to use local files to solve missions. More info in a blog post.

In order to install CheckiO client you'll need installed Python (version at least 3.8)

Install CheckiO Client first:

pip3 install checkio_client

Configure your tool

checkio --domain=py config --key=

Sync solutions into your local folder

checkio sync

(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)

checkio serv -d

Alternatevly, you can install Chrome extension or FF addon

checkio install-plugin
checkio install-plugin --ff
checkio install-plugin --chromium

Read more here about other functionality that the checkio client provides. Feel free to submit an issue in case of any difficulties.
